1. A circuit for load balancing and distributing switch-on control of an operating device, comprising:

  • a micro-controller that is able to couple to the operating device and to a power-in bus for receiving power from a power source, an electronically controlled switch coupled to the micro-controller for selectably applying power from a power-in bus to a power-out bus that is coupled to the operating device, and a noise diode that generates noise which is applied as an input to the micro-controller, wherein the micro-controller;

    samples the noise over a pre-determined time interval to obtain a random number that has a number of bits corresponding to the pre-determined time interval, and generates a power-up delay time period based on the random number.
